Seeking advice how to rotational play with University and other households.

I'm rotating with 10 families, when I have students study from home, I switch families on Friday about 5 pm because of uni. So they have all finished their terms on Friday, but don't enroll until I play the family again.
When there are some students in different families I sometimes have them enroll in a dorm together. First the student of the family that is to be played and then all the others who are waiting for their turn to enroll again. Then I play them at uni untill all have got their degrees.
